A Chicago commuter train collided with rail equipment Thursday morning, injuring at least 19 people, three of them seriously, a fire official said.

The Chicago Fire Department said a Chicago Transit Authority train crashed into a piece of equipment that was on the rails just before 11 a.m. on the city's North Side.

Three people suffered serious injuries while 16 others had non-life-threatening injuries, fire department spokesman Larry Langford, told the Chicago Sun-Times.

"That’s probably going to go up," Langford said of the injured.

At least 15 ambulances were dispatched to the scene of a train collision, located near the Howard CTA station.
